Abstract

The stack-forming device (10) has a stacking shaft (20) which is closed at the bottom by slide plates (22) and to which the printed products (16) are fed by means of the conveying device (14). Above the slide plates (22), intermediate base elements (58) can be slid into the stacking shaft (20), on which intermediate base elements (58), at the commencement of pre-stack formation, the fed printed products (16) are deposited one on top of the other. As soon as a specific number of printed products have been stacked, the intermediate base elements (58) are withdrawn from the stacking shaft (20), as a result of which the stacked printed products (16) fall onto the slide plates (22) and the pre-stack is completed with the feeding of further printed products (16). The finished pre-stack is then deposited on the delivery table (30) by moving apart the slide plates (22). The delivery table (30) is lowered and, as soon as the pre-stack has passed the intermediate base elements (58), the latter are moved back into the stacking shaft (20) to allow formation of a new pre-stack. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Bilden von Stapeln aus gefalteten Druckereiprodukten, wie Zeitungen, Zeitschriften und dergleichen, gemäss dem Oberbegriff des Anspruchs 1 und ein Verfahren zum Betrieb dieser Vorrichtung.The present invention relates to a device for forming stacks from folded printed products, such as newspapers, magazines and the like, according to the preamble of claim 1 and a method for operating this device.

Eine Vorrichtung dieser Art ist aus der DE-A-27 52 513 und der entsprechenden CA-A-1,091,707 bekannt. Eine Anzahl Druckereiprodukte wird jeweils in Schuppenformation mittels eines Bandförderers einem unten durch Schieberplatten verschlossenen Stapelschacht zugeführt, wo aus den Druckereiprodukten ein Vorstapel gebildet wird. Dann wird das Zuführen von Druckereiprodukten in den Stapelschacht unterbrochen und die Schieberplatten werden auseinandergezogen um den Vorstapel in einen Aufnahmeraum einer Paketbildeeinheit auf einen diesen gegen unten abschliessenden, heb- und senkbaren Ablagetisch bzw. bereits auf diesen abgelegte Vorstapel fallenzulassen. Dann wird der Stapelschacht durch gegeneinanderschieben der Schieberplatten unten wieder verschlossen, so dass der Bandförderer wiederum eine Anzahl Druckereiprodukte zur Bildung eines Vorstapels zuführen kann. Der Ablagetisch wird zusammen mit dem Aufnahmeraum jeweils nach der Uebernahme eines Vorstapels um 180o um die vertikale Achse gedreht, um einen Fertigstapel aus gegeneinanderverdrehten Vorstapeln zu bilden. Nach dem Drehen wird jeweils der Ablagetisch angehoben um die im Aufnahmeraum vorhandenen Druckereiprodukte zwischen sich und den Schieberplatten zusammenzupressen. Anschliessend wird der Ablagetisch soweit abgesenkt, dass die Druckereiprodukte nicht mehr an den Schieberplatten anliegen, so dass nun der nächste Vorstapel aufgenommen werden kann. Sobald ein vollständiger Fertigstapel gebildet ist, wird der Ablagetisch ganz abgesenkt und der Fertigstapel mittels einer Ausstosseinrichtung aus dem Aufnahmeraum ausgestossen.A device of this type is known from DE-A-27 52 513 and the corresponding CA-A-1,091,707. A number of printed products are fed in a scale formation by means of a belt conveyor to a stacking shaft closed at the bottom by slide plates, where a pre-stack is formed from the printed products. Then the feeding of printed products into the stacking shaft is interrupted and the slide plates are pulled apart in order to drop the pre-stack into a receiving space of a package forming unit on a storage table that can be lifted and lowered against the bottom or on the pre-stack already deposited on it. Then the stacking shaft is closed again by pushing the slide plates against one another at the bottom, so that the belt conveyor can in turn feed a number of printed products to form a pre-stack. The storage table, together with the receiving space, is rotated by 180 o about the vertical axis after a pre-stack has been taken over, in order to form a finished stack of pre-stacks twisted against one another. After turning, the storage table is raised by the print products available in the recording room between them and the slide plates. The storage table is then lowered to such an extent that the printed products no longer lie against the slide plates, so that the next pre-stack can now be picked up. As soon as a complete finished stack has been formed, the storage table is lowered completely and the finished stack is ejected from the receiving space by means of an ejection device.

Ueblicherweise fallen in einem Druckereiprodukte verarbeitenden Betrieb die Druckereiprodukte kontinuierlich an. Um diese kontinuierlich anfallenden Druckereiprodukte nun in der notwendigen Anzahl jeweils dem Stapelschacht zuführen zu können, wird entweder dem Bandförderer eine Lückenbildeeinrichtung zugeordnet oder es werden mehrere hintereinandergeschaltete Stapelbildeeinrichtungen vorgesehen, deren Stapelschächte abwechslungsweise mit der entsprechenden Anzahl Druckereiprodukte versorgt werden. Bei der Verwendung einer Lückenbildeeinrichtung wird die Lücke durch die Zeit bestimmt, die die Stapeleinrichtung benötigt, um einen Vorstapel der Paketbildeeinheit zu übergeben und den Stapelschacht mit den Schieberplatten wieder zu verschliessen. Während dieser Zeit werden die kontinuierlich anfallenden Druckereiprodukte gestaut, was die Geschwindigkeit mit der sie anschliessend dem Stapelschacht zugeführt werden können, sowie die Qualität des Vorstapels negativ beeinflussen kann. Schlussendlich wird die Verarbeitungskapazität durch die genannte Zeit mitbestimmt.Usually, the printing products are produced continuously in a printing products processing company. In order to be able to feed these continuously occurring printed products to the stacking chute in each case, either the belt conveyor is assigned a gap-forming device or several stacking devices connected in series are provided, the stacking chutes of which are alternately supplied with the corresponding number of printed products. When using a gap-forming device, the gap is determined by the time it takes for the stacking device to transfer a pre-stack to the packet-forming unit and to close the stack shaft again with the slide plates. During this time, the continuously occurring printed products are jammed, which can affect the speed at which they can subsequently be fed to the stacking shaft and the quality of the pre-stack. Finally, the processing capacity is determined by the time mentioned.

Wird jeweils die für einen Vorstapel notwendige Anzahl Druckereiprodukte abwechslungsweise mehreren Stapelschächten zugeführt, so wird die Zeit während der einem Stapelschacht keine Druckereiprodukte zugeführt werden können wiederum durch den Zeitbedarf bestimmt, der benötigt wird, um einen Vorstapel der Paketbildeeinheit zu übergeben und den Stapelschacht mittels den Schieberplatten wieder zu verschliessen. Schlussendlich wird die Anzahl benötigter Stapelbildeeinrichtungen durch diese Zeit mitbestimmt.If the number of printed products required for a pre-stack is alternately fed to several stacking chutes, the time during one stacking chute becomes no printed products can in turn be determined by the time required to transfer a pre-stack to the package forming unit and to close the stacking shaft again by means of the slide plates. Ultimately, the number of stacking devices required is also determined by this time.

Es ist somit ein Bedürfnis die Zeit während der einem Stapelschacht keine Druckereiprodukte zugeführt werden können, möglichst klein zu halten.It is therefore a requirement to keep the time during which no printed products can be fed to a stacking shaft as small as possible.

Eine weitere Stapelbildeeinrichtung mit einem unten durch Schieberplatten verschliessbaren Stapelschacht, in welchem eine Anzahl Druckereiprodukte zu einem Vorstapel gestapelt werden, ist aus der EP-A-0 348 610 und der entsprechenden US-A-5,002,456 bekannt. Damit der jeweils letzte der unter den Schieberplatten angeordneten Paketbildeeinheit übergebene Vorstapel vor dem Ausstossen des Fertigstapels aus dem Aufnahmeraum nicht zwischen dem Ablagetisch und den Schieberplatten zusammengepresst werden muss, und trotzdem die notwendige Stabilität des Fertigstapels erreicht wird, lehrt dieser Stand der Technik, die Druckereiprodukte mit dem Falz voraus dem Stapelschacht zuzuführen und auf der dem Falz gegenüberliegenden Seite im Mittelbereich durch ein in den Stapelschacht einschwenkbares Stützelement abzustützen. Die Druckereiprodukte nehmen dabei im dem Falz gegenüberliegenden Bereich eine dachartige Form ein. Dadurch kann wohl die Verarbeitungszeit in der Paketbildeeinheit, nicht aber die Zeit für das Entleeren des Stapelschachtes und wieder Schliessen durch die Schieberplatten verkürzt werden.A further stack forming device with a stack shaft which can be closed at the bottom by slide plates and in which a number of printed products are stacked to form a pre-stack is known from EP-A-0 348 610 and the corresponding US-A-5,002,456. This prior art teaches the printed products so that the last of the pre-stacks transferred under the slide plates arranged under the slide plates does not have to be pressed between the storage table and the slide plates before the finished stack is ejected from the receiving space, and nevertheless the necessary stability of the finished stack is achieved to feed the fold to the stacking shaft and to support it on the side opposite the fold in the central area by means of a support element that can be swiveled into the stacking shaft. The printed products take on a roof-like shape in the area opposite the fold. As a result, the processing time in the package forming unit can be reduced, but not the time for emptying the stacking shaft and closing it again by means of the slide plates.

Aus der DE-OS-31 30 945 und der entsprechenden US-A-4,445,681 ist eine Vorrichtung zum Herauslösen der mittels eines Greiferförderers mit grosser Geschwindigkeit geförderten Druckereiprodukte aus dem Förderstrom bekannt. Bei der Auslöseeinrichtung für die Greifer des Greiferförderers ist ein Anschlag vorgesehen, der beim Ein- bzw. Ausschalten der Auslöseeinrichtung in den Förderweg der Erzeugnisse einfahrbar bzw. aus diesem Förderweg ausfahrbar ist. Die aus dem Förderstrom herausgelösten und am Anschlag gebremsten Druckereiprodukte fallen direkt in einen Stapelschacht einer Stapelbildeeinrichtung zum Bilden eines Vorstapels.From DE-OS-31 30 945 and the corresponding US-A-4,445,681 a device for releasing the printed products conveyed at high speed by means of a gripper conveyor from the conveying stream is known. A stop is provided in the release device for the grippers of the gripper conveyor, which stop can be moved into or out of the delivery path of the products when the release device is switched on or off. The printed products released from the flow and braked at the stop fall directly into a stacking shaft of a stacking device for forming a pre-stack.

Schlussendlich sind Vorrichtungen zum Bilden von Stapeln aus ununterbrochen anfallenden Druckereiprodukten aus der CH-A-648 262 bzw. der entsprechenden US-A-4,432,685 und der CH-A-566 928 bekannt. Die Vorrichtung gemäss den beiden erstgenannten Dokumenten weist zwei um eine vertikale Achse drehbare und mit einem heb- und senkbaren Stapeltisch unten abgeschlossene Stapelschächte auf, die im Gegentakt zwischen einer Aufnahmestellung am Auslass einer als Bandförderer ausgebildeten Fördereinrichtung und einer Abgabestellung unterhalb einer von unten mit Vorstapeln beschickbaren Paketbildeeinheit bewegbar sind. Oberhalb der sich in Aufnahmestellung befindlichen Stapelschächte ist eine Zwischenstapeleinrichtung vorgesehen, die während der Bewegung der Stapelschächte zur Bildung eines Zwischenstapels aus den zugeführen Druckereiprodukten einschaltbar ist. Diese Zwischenstapeleinrichtung erfüllt denselben Zweck wie die weiter oben erwähnte Lückenbildeeinrichtung, nämlich kontinuierlich anfallende Druckereiprodukte während einer Zeit, in der sie keinem Stapelschacht zugeführt werden können, zwischenzuspeichern. Auch in der CH-A-566 928 wird vorgeschlagen, eine Zwischenspeichereinrichtung vorzusehen um die kontinuierlich zugeführten Druckereiprodukte stapelförmig zwischenzuspeichern, während der Zeit die benötigt wird, um einen Vorstapel aus einem Stapelschacht einer unterhalb diesem angeordneten Paketbildeeinheit zu übergeben und den Stapelschacht wieder zu verschliessen. Der Stapelschacht ist dabei durch einen geneigten, aus zwei gegensinnig
aber im Gleichtakt verschwenkbaren Rechen gebildeten Rost verschliessbar. Die Zwischenstapeleinrichtung weist ein rechenartig ausgebildetes Trennorgan auf, das sobald ein Vorstapel gebildet ist, in den Weg der den Auslass einer als Bandförderer ausgebildeten Fördereinrichtung verlassenden Druckereiprodukte eingeschwenkt, so dass diese nicht in den Stapelschacht fallen können. Gleichzeitig mit dem Einschwenken setzt eine Abwärtsbewegung des Trennorgans ein. Dieser dauert solange bis das zuletzt dem Stapelraum zur Bildung eines Vorstapels zugeführte Druckereiprodukt die gestapelten Druckereiprodukte erreicht hat und der Vorstapel durch eine Drehung der Tragrechen an die Paketbildeeinheit freigegeben wurde. In dieser Zeit bildet sich auf dem sich absenkenden Trennorgan ein Teilstapel, der dann auf die Tragrechen fallengelassen wird, ohne dass es zu einem Stau in der Fördereinrichtung kommt oder die Zuführung der Druckereiprodukte unterbrochen werden muss.Finally, devices for forming stacks from continuously occurring printed products are known from CH-A-648 262 or the corresponding US-A-4,432,685 and CH-A-566 928. The device according to the first two documents mentioned has two stacking chutes, which can be rotated about a vertical axis and closed at the bottom with a lifting and lowering stacking table, which, in counter-clockwise motion, between a receiving position at the outlet of a conveyor device designed as a belt conveyor and a delivery position below one which can be pre-stacked from below Package forming unit are movable. An intermediate stacking device is provided above the stacking shafts in the receiving position, which can be switched on during the movement of the stacking shafts to form an intermediate stack from the supplied printed products. This intermediate stacking device fulfills the same purpose as the gap formation device mentioned above, namely continuously occurring printing products during a time in which it does not have a stacking shaft can be supplied to buffer. Also in CH-A-566 928 it is proposed to provide an intermediate storage device in order to temporarily store the continuously supplied printed products in a stack, while the time is required to transfer a pre-stack from a stacking shaft to a packet-forming unit arranged below it and to close the stacking shaft again. The stacking shaft is inclined by one, two in opposite directions
but rust formed in the same time pivotable rake closable. The intermediate stacking device has a rake-like separating element which, as soon as a pre-stack is formed, is pivoted into the path of the printed products leaving the outlet of a conveyor device designed as a belt conveyor, so that they cannot fall into the stacking shaft. At the same time as the swiveling in, a downward movement of the separating element begins. This lasts until the printed product that was last fed to the stacking space to form a pre-stack has reached the stacked printed products and the pre-stack has been released to the package-forming unit by rotating the supporting rake. During this time, a partial stack is formed on the lowering separating element, which is then dropped onto the supporting rakes without causing a jam in the conveyor device or the supply of the printed products having to be interrupted.

Eine Vorrichtung zum Bilden von Stapeln aus Kunststoffbeuteln oder Tragtaschen ist in der DE-A-23 57 658 offenbart. Unterhalb eines in den Stapelschacht ein- und aus diesem ausfahrbaren Bodens ist ein, ebenfalls in den Stapelschacht ein- und ausfahrbarer Zwischenboden angeordnet, dessen vertikaler Abstand zum Boden mindestens der Höhe eines fertigen Stapels entspricht. Die Stapelbildung beginnt auf dem in den Stapelschacht eingefahrenen Boden, so dass die von einer Fördereinrichtung abgeworfenen Beutel oder Tragtaschen nur eine geringe Fallhöhe zu überwinden haben. Vor Erreichen der gewünschten Stapelhöhe wird der Boden geöffnet, so dass der Stapel auf den geschlossenen Zwischenboden fällt. Sobald der Stapel auf dem Zwischenboden fertig gebildet ist, wird der Boden in den Stapelschacht eingefahren, so dass sich auf diesem der nächste Stapel zu bilden beginnt. Nachdem der Boden eingefahren ist, wird durch Oeffnen des Zwischenbodens der Stapel auf ein intermittierend oder kontinuierlich umlaufendes Stapelband zum Wegführen abgesetzt. Anschliessend wird der Zwischenboden wieder geschlossen, damit dieser den folgenden Stapel aufnehmen kann. Diese bekannte Vorrichtung lässt die kontinuierliche Zuführung der Beutel oder Tragtaschen zu, doch ist nur die Bildung von Stapeln kleiner Höhe möglich.A device for forming stacks from plastic bags or carrier bags is disclosed in DE-A-23 57 658. Arranged underneath a floor which can be moved into and out of the stacking shaft is an intermediate floor which can also be moved in and out of the stacking shaft, whose vertical distance from the floor corresponds at least to the height of a finished stack. The stack formation begins on the floor retracted into the stacking shaft, so that the bags or carrier bags thrown off by a conveyor device only have to overcome a small drop height. Before the desired stack height is reached, the floor is opened so that the stack falls onto the closed intermediate floor. As soon as the stack has been formed on the intermediate floor, the floor is moved into the stacking shaft so that the next stack begins to form on it. After the floor has been retracted, the stack is placed on an intermittently or continuously rotating stacking belt for removal by opening the intermediate floor. The intermediate floor is then closed again so that it can accommodate the following stack. This known device allows the bags or carrier bags to be fed continuously, but only the formation of stacks of small height is possible.

Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine gattungsgemässe Vorrichtung zu schaffen, bei welcher die Zeit während der dem Stapelschacht keine Druckereiprodukte zugeführt werden können, möglichst kurz ist.Starting from this prior art, it is an object of the present invention to provide a generic device in which the time during which no printed products can be fed to the stacking shaft is as short as possible.

Diese Aufgabe wird durch eine Vorrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist.This object is achieved by a device which has the features of claim 1.

Der erfindungsgemässe, in den Stapelschacht ein- und aus diesem ausfahrbare Zwischenboden ermöglicht es, Druckereiprodukte dem Stapelschacht zuzuführen, bevor die Schieberplatten nach dem Entleeren des Stapelschachtes diesen wieder verschliessen können. Zusätzlich zum Zeitgewinn wird auch die Fallhöhe der Druckereiprodukte verringert, was zu hochqualitativen Stapeln führt. Diese Verringerung der Fallhöhe erlaubt es auch, hohe Stapelschächte zum Bilden grosser Vorstapel vorzusehen. Ueber dies können infolge der geringen Fallhöhe mehrblätterige, dicke Druckereiprodukte, die mit hoher Geschwindigkeit zugeführt werden, zu qualitativ guten Vorstapeln gestapelt werden.The intermediate floor according to the invention, which can be moved into and out of the stacking shaft, makes it possible to supply printed products to the stacking shaft before the slide plates after emptying the stacking shaft you can close it again. In addition to saving time, the drop height of the printed products is also reduced, which leads to high-quality stacks. This reduction in the drop height also makes it possible to provide high stacking shafts for forming large pre-stacks. As a result of the low drop height, multi-sheet, thick printed products that are fed at high speed can be stacked to good quality pre-stacks.

Weitere bevorzugte Ausbildungsformen der erfindungsgemässen Vorrichtung sind in den abhängigen Ansprüchen angegeben.Further preferred embodiments of the device according to the invention are specified in the dependent claims.

Ein bevorzugtes Verfahren zum Betrieb der Vorrichtung ist im Anspruch 11 definiert.A preferred method for operating the device is defined in claim 11.

Die Erfindung wird nun an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. Es zeigen rein schematisch:

The invention will now be described with reference to an embodiment shown in the drawing. It shows purely schematically:
Fig. 1
in view and partly in section, two identical stacking devices arranged below a gripper conveyor;
2 and 3
in view or side view, partially cut and enlarged part of the gripper conveyor shown in Figure 1 and the one shown in Figure 1 stacking device; and

greatly simplified compared to FIGS. 1 to 3, a stacking device at six different points in time of a processing cycle.

Fig.1 zeigt zwei nebeneinander angeordnete Stapelbildeeinrichtungen 10, über welche hinweg eine als Greiferförderer 12 ausgebildete Fördereinrichtung 14 zum Zuführen von Druckereiprodukten 16 zu den Stapelbildeeinrichtungen 10 führt.1 shows two stack-forming devices 10 arranged next to one another, over which a conveyor device 14 designed as a gripper conveyor 12 leads to the stack-forming devices 10 for feeding printed products 16.

Jede Stapelbildeeinrichtung 10 weist einen von Begrenzungsleisten 18 festgelegten, vertikalen Stapelschacht 20 auf, der unten mittels in horizontaler Richtung aufeinander zu und voneinander weg bewegbaren Schieberplatten 22 verschliessbar ist. Unterhalb der Schieberplatten 22 schliesst ein auf zwei einander gegenüberliegenden Seiten durch Führungsleisten 24 begrenzter Aufnahmeraum 26 einer Paketbildeeinheit 28 an. Der Aufnahmeraum 26 ist unten von einem heb- und senkbaren Ablagetisch 30 begrenzt, der zusammen mit den Führungsleisten 24 auch um eine vertikale Achse 32 drehbar ist. Der Antrieb für den Ablagetisch 30 ist schematisch angedeutet und mit 33 bezeichnet. Die Begrenzungsleisten 18 des Stapelschachtes 20 sind an einem fahrbaren Gestell 34 in bekannter Art und Weise einstellbar angeordnet um den Stapelschacht 20 an das Format der zu verarbeitenden Druckereiprodukte anzupassen. Am selben Gestell 34 ist auch die Paketbildeeinheit 28 mit samt dem Antrieb 33 in bekannter Art und Weise angeordnet.Each stacking device 10 has a vertical stacking shaft 20 which is defined by boundary strips 18 and which can be closed at the bottom by means of slide plates 22 which can be moved towards and away from one another in the horizontal direction. Below the slide plates 22 there is a receiving space 26 of a packet forming unit 28 which is delimited on two opposite sides by guide strips 24. The receiving space 26 is delimited at the bottom by a lifting and lowering storage table 30 which, together with the guide strips 24, can also be rotated about a vertical axis 32. The drive for the storage table 30 is indicated schematically and designated 33. The limiting strips 18 of the stacking shaft 20 are arranged on a movable frame 34 in a known manner so as to be adjustable in order to adapt the stacking shaft 20 to the format of the printed products to be processed. At the same Frame 34 is also the packet forming unit 28 with the drive 33 arranged in a known manner.

Weiter weist die Stapelbildeeinrichtung 10 eine Ausstosseinrichtung 36 auf, um die jeweils in der Paketbildeeinheit 28 gebildeten Fertigstapel 38 aus dem Aufnahmeraum 26 zur Weiterverarbeitung auszustossen. Was insoweit den Aufbau und die Funktionsweise der Stapelbildeeinrichtung 10 betrifft, wird ausdrücklich auf die DE-A-27 52 513 bzw. die entsprechende CA-A-1,091,707, die CH-A-623 286, die CH-A-623 288 bzw. die entsprechende US-A-4,214,743 und die CH-A-623 287 bzw. die entsprechende US-A-4,229,134 verwiesen.Furthermore, the stack forming device 10 has an ejection device 36 in order to eject the finished stacks 38 formed in each case in the packet forming unit 28 from the receiving space 26 for further processing. As far as the structure and mode of operation of the stacking device 10 are concerned, reference is expressly made to DE-A-27 52 513 and the corresponding CA-A-1,091,707, CH-A-623 286, CH-A-623 288 and the corresponding US-A-4,214,743 and CH-A-623 287 and the corresponding US-A-4,229,134, respectively.

Der Greiferförderer 12 weist im bekannter Art und Weise an einem in einem Kanal 40 geführten Zugorgan 42 in einem festen Abstand hintereinander angeordnete einzelsteuerbare Greifer 44 auf. Das Zugorgan 42 ist in Förderrichtung F umlaufend angetrieben und die Greifer 44 weisen entgegen der Förderrichtung F gerichtete Mäuler auf, um die Druckereiprodukte 16 einzelweise im Bereich ihrer vorlaufenden Kante 46 gehalten zu transportieren.The gripper conveyor 12 has, in the known manner, individually controllable grippers 44 arranged one behind the other at a fixed distance on a traction element 42 guided in a channel 40. The traction element 42 is driven in a rotating manner in the conveying direction F and the grippers 44 have mouths directed against the conveying direction F in order to transport the printed products 16 individually held in the region of their leading edge 46.

Die Fördereinrichtung 14 weist weiter oberhalb jeder Stapelbildeeinrichtung 10 eine Herauslöseeinrichtung 48 zum wahlweise Herauslösen von Druckereiprodukten 16 aus dem Förderstrom auf. Eine ein- und ausschaltbare Auslöseeinrichtung 50 der Herauslöseeinrichtung 48 öffnet im eingeschalteten Zustand die vorbeilaufenden Greifer 44, so dass diese das jeweilige Druckereiprodukt 16 freigeben. Jeder Auslöseeinrichtung 50 ist ein Anschlagorgan 52 zugeordnet, das beim Ein- bzw. Ausschalten der Auslöseeinrichtung 50 in den Förderweg der Druckereiprodukte 16 einfahrbar bzw. aus diesem Förderweg ausfahrbar ist. Die aus dem Förderstrom herausgelösten Druckereiprodukte 16 schlagen mit ihrer vorlaufenden Kante 46 am Anschlagorgan 52 an, wodurch diese abgebremst werden und von oben in den Stapelschacht 20 der entsprechenden Stapelbildeeinrichtung 10 fallen. Was den Aufbau und die Funktionsweise der Fördereinrichtung 14 mit der Herauslöseeinrichtung 48 betrifft, wird ausdrücklich auf die DE-A-31 30 945 und die entsprechende US-A-4,445,681 verwiesen.The conveying device 14 furthermore has a detaching device 48 above each stack forming device 10 for selectively detaching printed products 16 from the conveying stream. A triggering device 50 of the triggering device 48, which can be switched on and off, opens the passing grippers 44 in the switched-on state, so that they release the respective printed product 16. Each triggering device 50 is assigned a stop element 52 which, when the triggering device 50 is switched on or off is retractable into the conveyor path of the printed products 16 or can be extended from this conveyor path. The leading edge 46 of the printed products 16 detached from the feed stream strikes the stop member 52, as a result of which they are braked and fall into the stacking shaft 20 of the corresponding stacking device 10 from above. Regarding the construction and the mode of operation of the conveyor 14 with the release device 48, reference is expressly made to DE-A-31 30 945 and the corresponding US-A-4,445,681.

Eine bestimmte Anzahl von Druckereiprodukten 16 wird jeweils mittels der Herauslöseeinrichtung 48 aus dem vom Greiferförderer 12 in Förderrichtung F transportierten Förderstrom herausgelöst, und aus diesen Druckereiprodukten 16 wird im Stapelschacht 20 der entsprechenden Stapelbildeeinrichtung 10 ein Vorstapel 54 gebildet, siehe auch Fig. 2 und 3. Durch das Auseinanderfahren der beiden Schieberplatten 22 fällt dann der jeweilige Vorstapel 54 auf den Ablagetisch 30 bzw. die breits sich darauf befindenden Vorstapel 54' zur Bildung eines Fertigstapels 38 mit gegeneinander um jeweils 180o verdrehten Vorstapeln 54'.A certain number of printed products 16 are released from the conveying stream transported by the gripper conveyor 12 in the conveying direction F by means of the release device 48, and a pre-stack 54 is formed from these printed products 16 in the stacking shaft 20 of the corresponding stacking device 10, see also FIGS. 2 and 3. by the moving apart of the two slide plates 22 then the respective pre-stack 54 falls onto the delivery table 30 or the breits to it that are available pre-stack 54 'to form a finished stack 38 with mutually o twisted by 180 pre-stacking 54'.

Wie dies aus der Fig. 1, insbesondere aber aus den Fig. 2 und 3 hervorgeht, weist die Stapelbildeeinrichtung 10 einen Zwischenboden 56 auf, der in einem Abstand A oberhalb der Schieberplatten 22 in horizontaler Richtung in den Stapelschacht 20 ein- und aus diesem ausfahrbar ist. Er weist zwei in Pfeilrichtung B aufeinander zu und voneinander weg schiebbare Zwischenbodenelemente 58 auf, die, wie dies besonders deutlich aus der Fig. 2 hervorgeht, gabelartig ausgebildet sind, um beidseitig der entsprechenden Begrenzungsleisten 18 in den Stapelschacht 20 eingreifen zu können. Die Zwischenbodenelemente 58 sind an am Gestell 34 abgestützten Führungselementen 60 verschiebbar gelagert und je an ein Zylinder-Kolbenaggregat 62 gekoppelt. Die Zwischenbodenelemente 58 sind in derselben Bewegungsrichtung B hin und her verschiebbar wie die beiden Schieberplatten 22, deren Bewegungsrichtungen mit dem Doppelpfeil C angedeutet sind. Die in C-förmigen, am Gestell 34 befestigten Führungsschienen 64 verschiebbar gelagerten Schieberplatten 22 sind ebenfalls je mit einem weiteren Zylinder-Kolbenaggregat 66 verbunden.As can be seen from FIG. 1, but in particular from FIGS. 2 and 3, the stack-forming device 10 has an intermediate floor 56 which can be moved into and out of the stacking shaft 20 in the horizontal direction at a distance A above the slide plates 22 is. It has two intermediate floor elements 58 which can be pushed towards and away from each other in the direction of arrow B and which, as can be seen particularly clearly from FIG. 2, are fork-like are designed to be able to engage on both sides of the corresponding boundary strips 18 in the stacking shaft 20. The intermediate floor elements 58 are displaceably mounted on guide elements 60 supported on the frame 34 and are each coupled to a cylinder-piston unit 62. The intermediate floor elements 58 can be moved back and forth in the same direction of movement B as the two slide plates 22, whose directions of movement are indicated by the double arrow C. The slide plates 22, which are displaceably mounted in C-shaped guide rails 64 fastened to the frame 34, are also each connected to a further cylinder-piston unit 66.

Die Zylinder-Kolbenaggregate 62 und weiteren Zylinder-Kolbenaggregate 66 werden von einer Steuereinrichtung 68 angesteuert, wie dies mit den strichpunktiert gezeichneten Leitungen 70, 70' angedeutet ist. Dieselbe Steuereinrichtung 68 steuert auch die Herauslöseeinrichtung 48 mit der Auslöseeinrichtung 50 und dem Anschlagorgan 52, als auch den Antrieb 33 des Ablagetisches 30, wie dies mit den strichpunktierten Leitungen 74, 74' angedeutet ist, und die Ausstosseinrichtung 36.The cylinder-piston assemblies 62 and further cylinder-piston assemblies 66 are controlled by a control device 68, as is indicated by the lines 70, 70 'shown in broken lines. The same control device 68 also controls the release device 48 with the release device 50 and the stop element 52, as well as the drive 33 of the storage table 30, as indicated by the dash-dotted lines 74, 74 ', and the ejection device 36.

Dem Stapelschacht 20 jeder Stapelbildeeinrichtung 10 ist ein Biegeorgan 76 zugeordnet, das in Förderrichtung F dem betreffenden Stapelschacht 20 vorgelagert und am Gestell 34 angeordnet ist. Das Biegeorgan 76 weist ein dachartig geformtes Lochblech 78 auf, dessen Biegelinie sich etwa in Förderrichtung F erstreckt. Die im Bereich ihrer vorlaufenden Kante 46 gehaltenen, schräg nach hinten hängend transportierten Druckereiprodukte 16 werden in ihrem nachlaufenden Endbereich 80 vom Lochblech 78 abgestützt, wodurch die Druckereiprodukte 16 um eine etwa in Förderrichtung F verlaufende Biegelinie dachartig gebogen werden, wie dies insbesondere aus der Fig. 3 ersichtlich ist und auch in der DE-A-31 30 945 bzw. der entsprechenden US-A-4,445,681 beschrieben und gezeigt ist. Dies vermittelt den Druckereiprodukten 16 eine hohe Eigenstabilität um ein Verletzen beim Anstossen am Anschlagorgan 52 zu verhindern und gewährleistet einen stabilen Fall in den Stapelschacht 20. Das Lochblech 78 ist über eine schematisch angedeutete Vakuumleitung 82 mit einer nichtgezeigten Unterdruckquelle verbunden, um auf die aus dem Förderstrom herauszulösenden Druckereiprodukte 16 eine Bremswirkung auszuüben. Dies erlaubt zusammen mit Anschlagorgan 52, selbst mit hoher Geschwindigkeit zugeführte, dicke, vielblättrige Druckereiprodukte 16 aus dem Förderstrom herauszulösen und in den jeweiligen Stapelschacht 20 fallenzulassen.The stacking shaft 20 of each stacking device 10 is assigned a bending member 76, which is arranged upstream of the stacking shaft 20 in question in the conveying direction F and is arranged on the frame 34. The bending member 76 has a roof-shaped perforated plate 78, the bending line of which extends approximately in the conveying direction F. The printed products 16 which are held in the region of their leading edge 46 and are transversely suspended and are supported in their trailing end region 80 by the perforated plate 78, as a result of which the Printed products 16 are bent roof-like around a bending line running approximately in the conveying direction F, as can be seen in particular from FIG. 3 and is also described and shown in DE-A-31 30 945 and the corresponding US-A-4,445,681. This gives the printed products 16 a high degree of intrinsic stability in order to prevent injury when they strike the stop member 52 and ensures a stable fall into the stacking shaft 20. The perforated plate 78 is connected via a schematically indicated vacuum line 82 to a vacuum source (not shown) in order to refer to the from the flow to be released printing products 16 exert a braking effect. Together with the stop element 52, this allows thick, multi-leaf printed products 16, even those fed at high speed, to be removed from the conveying flow and dropped into the respective stacking shaft 20.

Die Funktionsweise der in den Fig. 1 bis 3 gezeigten Vorrichtung wird nun an Hand der Fig. 4 bis 9 beschrieben. Diese zeigen stark vereinfacht jeweils den Stapelschacht 20 mit den beiden Schieberplatten 22 und den Zwischenbodenelementen 58, sowie von der Paketbildeeinheit 28 den Aufnahmeraum 26 mit dem Ablagetisch 30. Zusätzlich ist in der Fig. 5 der die Druckereiprodukte 16 zuführende Greiferförderer 12 angedeutet.The operation of the device shown in FIGS. 1 to 3 will now be described with reference to FIGS. 4 to 9. These show, in a highly simplified manner, the stacking shaft 20 with the two slide plates 22 and the intermediate floor elements 58, as well as the receiving space 26 with the storage table 30 from the package forming unit 28. In addition, the gripper conveyor 12 feeding the printed products 16 is indicated in FIG. 5.

Bei Inbetriebnahme der Stapelbildeeinrichtung 10 sind die Zwischenbodenelemente 58 in den Stapelschacht 20 eingefahren, und dieser ist unten durch die bis zu einem Spalt aufeinanderzu verschobenen Schieberplatten 22 verschlossen. Der Ablagetisch 30 ist in seine obere Endlage angehoben, wo er sich mit einem geringen Abstand unterhalb der Schieberplatten 22 befindet, wie dies Fig. 4 zeigt. Nun wird die einer Stapelbildeeinrichtung 10 zugeordnete Herauslöseeinrichtung 48 eingeschaltet, wie dies in Fig. 1 bei der links gezeigten Stapelbildeeinrichtung 10 angedeutet ist. Dadurch werden nacheinander Druckereiprodukte 16 aus dem Förderstrom herausgelöst und diese fallen auf die Zwischenbodenelemente 58, wo sie gestapelt werden (vergleiche insbesondere Fig. 1 und 4). Sobald nun eine bestimmte Anzahl Druckereiprodukte 16 sich auf den Zwischenbodenelementen 58 befinden bzw. der dabei gebildete Teilvorstapel eine bestimmte Höhe erreicht hat, werden die Zwischenbodenelemente 58 voneinanderweg aus dem Stapelschacht 20 herausgezogen, was zur Folge hat, dass der Teilvorstapel auf die Schieberplatten 22 fällt (Fig. 5), dabei werden weitere Druckereiprodukte 16 zugeführt bis der im Stapelschacht 20 gebildete Vorstapel 54 die gewünschte Anzahl Druckereiprodukte 16 aufweist. Die Höhe des Vorstapels 54 kann dabei grösser sein als die lichte Weite zwischen dem Zwischenboden 56 und den Schieberplatten 22.When the stack-forming device 10 is put into operation, the intermediate floor elements 58 are moved into the stacking shaft 20, and this is closed at the bottom by the slide plates 22 which are pushed towards one another up to a gap. The storage table 30 is raised to its upper end position, where it is a short distance below the slide plates 22 is located, as shown in FIG. 4. Now the release device 48 assigned to a stack forming device 10 is switched on, as is indicated in FIG. 1 for the stack forming device 10 shown on the left. As a result, printed products 16 are released from the conveying stream one after the other and these fall onto the intermediate floor elements 58, where they are stacked (compare in particular FIGS. 1 and 4). As soon as a certain number of printed products 16 are located on the intermediate floor elements 58 or the partial preliminary stack formed thereby has reached a certain height, the intermediate floor elements 58 are pulled away from one another from the stacking shaft 20, with the result that the partial preliminary stack falls on the slide plates 22 ( 5), further printed products 16 are fed in until the pre-stack 54 formed in the stacking shaft 20 has the desired number of printed products 16. The height of the pre-stack 54 can be greater than the clear width between the intermediate floor 56 and the slide plates 22.

Sodann wird die Herauslöseeinrichtung 48 ausgeschaltet und die in der Fig. 1 der Stapelbildeeinrichtung 10 rechts zugeordnete Herauslöseeinrichtung 48 aktiviert, so dass nun im Stapelschacht 20 dieser Stapelbildeeinrichtung 10 ein Vorstapel 54 auf die genau gleiche Art und Weise gebildet werden kann. Der fertige Vorstapel 54 wird auf den Ablagetisch 30 abgelegt indem die Schieberplatten 22 auseinander gezogen werden sobald das letzte zugeführte Druckereiprodukt 16 den Vorstapel 54 vervollständigt hat. Wie dies in der Fig. 6 mit dem nach unten zeigenden Pfeil angedeutet ist, wird nun der Ablagetisch 30 abgesenkt und sobald der Vorstapel 54 die Zwischenbodenelemente 58 passiert hat, werden diese wieder in den Stapelschacht 20 eingefahren (Fig. 7). Nun kann auf diesen wieder die Bildung eines neuen Vorstapels 54 begonnen werden, während der Ablagetisch 30 soweit abgesenkt wird, dass der gesamte Vorstapel 54 in den Aufnahmeraum 26 eintaucht. Sodann werden der Stapelschacht 20 durch das Aufeinanderzufahren der Schieberplatten 22 unten wieder verschlossen und der Ablagetisch 30 zusammen mit dem Aufnahmeraum 26 und dem sich darin befindenden Vorstapel 54' um 180o um die vertikale Achse 32 gedreht wie dies in der Fig. 8 mit dem Pfeil angedeutet ist.Then the detaching device 48 is switched off and the detaching device 48 assigned to the right in FIG. 1 of the stacking device 10 is activated, so that a pre-stack 54 can now be formed in the stacking shaft 20 of this stacking device 10 in exactly the same way. The finished pre-stack 54 is placed on the storage table 30 by pulling the slide plates 22 apart as soon as the last printed product 16 supplied has completed the pre-stack 54. As indicated in FIG. 6 with the arrow pointing downward, the storage table 30 is now lowered and as soon as the pre-stack 54 has passed the intermediate floor elements 58, these are moved back into the stacking shaft 20 (FIG. 7). Now the formation of a new pre-stack 54 are started, while the storage table 30 is lowered so far that the entire pre-stack 54 is immersed in the receiving space 26. Then, the stacking shaft are sealed 20 by the collision closing of the slide plates 22 down again and the tray table 30 'o rotated together with the receiving space 26 and disposed therein prestack 54 by 180 about the vertical axis 32 as shown in Fig. 8 by the arrow is indicated.

Sobald nun die gewünschte Anzahl zugeführter Druckereiprodukte 16 auf den Zwischenbodenelementen 58 zu einem Teilvorstapel gestapelt sind, werden die Zwischenbodenelemente 58 wiederum aus dem Stapelschacht 20 gezogen und wird auf den Schieberplatten 22 unter Zuführung weiterer Druckereiprodukte 16 ein zweiter Vorstapel 54 fertiggestellt. Während dieser Zeit wird der Ablagetisch 30 angehoben, wie dies Fig. 9 zeigt, um den Vorstapel 54' zwischen sich und den Schieberplatten 22 zusammenzupressen. Dieses Zusammenpressen führt zu einem kompakten, stabilen Fertigstapel 38. Nach dem Pressen wird der Ablagetisch 30 wieder geringfügig abgesenkt, bis der Vorstapel 54' nicht mehr an den Schieberplatten 22 anliegt (etwa wie in Fig. 8 gezeigt).As soon as the desired number of supplied printed products 16 have been stacked on the intermediate floor elements 58 to form a partial preliminary stack, the intermediate floor elements 58 are in turn pulled out of the stacking shaft 20 and a second preliminary stack 54 is completed on the slide plates 22 with the supply of further printed products 16. During this time, the storage table 30 is raised, as shown in FIG. 9, in order to press the pre-stack 54 ′ between itself and the slide plates 22. This pressing together leads to a compact, stable finished stack 38. After pressing, the storage table 30 is again lowered slightly until the pre-stack 54 'no longer lies against the slide plates 22 (as shown in FIG. 8, for example).

Sobald nun im Stapelschacht 20 der zweite Vorstapel 54 fertig gebildet ist, werden die Schieberplatten 22 wieder auseinandergezogen, wodurch dieser Vorstapel 54 auf den sich im Aufnahmeraum 26 befindende Vorstapel 54' abgesetzt wird. Der Ablagetisch 30 wird dann abgesenkt, und die Zwischenbodenelemente 58 werden eingefahren, um die Bildung eines weiteren Vorstapels 54 zu ermöglichen, wie dies Fig. 1 an Hand der links gezeigten Stapelbildeeinrichtung 10 zeigt. In genau gleicher Art und Weise wie weiter oben beschreiben, werden dann die Schieberplatten 22 wieder eingefahren, die beiden aufeinanderliegenden Vorstapel 54, 54' um 180o um die vertikale Achse 32 gedreht und gepresst. Dies wiederholt sich, bis ein Fertigstapel 38 mit der gewünschten Anzahl Druckereiprodukte 16 aus gegeneinander verdreht aufeinanderliegender Vorstapel 54' gebildet ist. Zum Wegführen des Fertigstapels 38 wird der Ablagetisch 30 in seine untere Endlage abgesenkt, was bei der in der Fig. 1 rechts gezeigten Stapelbildeeinrichtung 10 der Fall ist. Sodann wird die Ausstosseinrichtung 36 aktiviert um den Fertigstapel aus dem Aufnahmeraum 26 zu stossen. Jener kann nun einer weiteren Verarbeitungsstation zugeführt werden.As soon as the second pre-stack 54 has now been formed in the stacking shaft 20, the slide plates 22 are pulled apart again, as a result of which this pre-stack 54 is placed on the pre-stack 54 'located in the receiving space 26. The storage table 30 is then lowered and the intermediate floor elements 58 are retracted to enable the formation of a further pre-stack 54, as shown in FIG. 1 using the stack-forming device 10 shown on the left. In exactly the same manner as further described above, the slide plates 22 are then retracted again, the two superimposed pre-stack 54 'o 54 is rotated by 180 about the vertical axis 32 and pressed. This is repeated until a finished stack 38 with the desired number of printed products 16 is formed from pre-stacks 54 'which are rotated one on top of the other. To remove the finished stack 38, the storage table 30 is lowered into its lower end position, which is the case with the stack forming device 10 shown on the right in FIG. 1. The ejection device 36 is then activated in order to eject the finished stack from the receiving space 26. It can now be fed to another processing station.

Der Vollständigkeit halber sei erwähnt, dass einem Stapelschacht 20 jeweils keine Druckereiprodukte 16 zugeführt werden können, wenn die Zwischenbodenelemente 58 und Schieberplatten 22 aus dem Stapelschacht 20 ausgefahren sind.For the sake of completeness, it should be mentioned that no stacked products 16 can be fed to a stacking shaft 20 if the intermediate floor elements 58 and slide plates 22 have been moved out of the stacking shaft 20.

Neben dem Aufsplitten des Produktestromes auf einander nachgeschaltete Stapelbildeeinrichtungen 10, wie dies in der Fig. 1 gezeigt ist, ist es auch denkbar, zwischen einer Druckereiprodukte 16 kontinuierlich zuführenden Fördereinrichtung 10, beispielsweise dem Greiferförderer 12, und dem Stapelschacht 20 einer Stapelbildeeinrichtung 10 eine Lückenbildeeinrichtung vorzusehen, wie dies z.B. in der DE-A-27 52 513 bzw. der entsprechenden CA-A-1,091,707 und der CH-A-623 286 offenbart ist. Selbstverständlich wäre es auch möglich mit der Fördereinrichtung sektionsweise einer Stapeleinrichtung 10 die gewünschte Anzahl Druckereiprodukte für die Bildung eines Vorstapels 54 zuzuführen und jeweils eine weitere Sektion zuzuführen sobald der Zwischenboden für den Beginn einer neuen Vorstapelbildung bereit ist.In addition to the splitting of the product stream onto stack-forming devices 10 connected one behind the other, as shown in FIG. 1, it is also conceivable to provide a gap-forming device between a conveyor device 10 that continuously feeds printed products 16, for example the gripper conveyor 12, and the stacking shaft 20 of a stack-forming device 10 , as disclosed for example in DE-A-27 52 513 or the corresponding CA-A-1,091,707 and CH-A-623 286. Of course, it would also be possible to section by section with the conveyor to feed the desired number of printed products for the formation of a pre-stack 54 to a stacking device 10 and to feed a further section as soon as the intermediate floor is ready for the start of a new pre-stack formation.

Bei ein- oder wenigblättrigen gefalteten Druckereiprodukten ist es eventuell nicht notwendig, die Vorstapel gegeneinander verdreht zu einem Fertigstapel aufeinander abzulegen. In diesem Fall wird der Antrieb 33 so angesteuert, dass der Ablagetisch 30 nur eine Heb- und Senkbewegung ausführt.In the case of single-page or short-page folded printed products, it may not be necessary to lay the pre-stacks on top of one another twisted to form a finished stack. In this case, the drive 33 is controlled such that the storage table 30 only carries out a lifting and lowering movement.

Der Zwischenboden kann nach Bedarf in Funktion gesetzt oder stillgelegt werden. Ebenfalls ist es möglich, unterschiedlich hohe Vorstapel zu bilden und diese zu einem Fertigstapel zusammenzubringen.The intermediate floor can be put into operation or shut down as required. It is also possible to form pre-stacks of different heights and to combine them into a finished stack.
